### Impact The vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream. ### Patches XStream 1.4.20 handles the stack overflow and raises an InputManipulationException instead. ### Workarounds The attack uses the hash code implementation for collections and maps to force recursive hash calculation causing a stack overflow. Following types of the Java runtime are affected: - java.util.HashMap - java.util.HashSet - java.util.Hashtable - java.util.LinkedHashMap - java.util.LinkedHashSet - Other third party collection implementations that use their element's hash code may also be affected A simple solution is to catch the StackOverflowError in the client code calling XStream. If your object graph does not use referenced elements at all, you may simply set the NO_REFERENCE mode: ```Java XStream xstream = new XStream(); xstream.setMode(XStream.NO_REFERENCES); ``` I...

XStream serializes Java objects to XML and back again. Versions prior to 1.4.20 may allow a remote attacker to terminate the application with a stack overflow error, resulting in a denial of service only via manipulation the processed input stream. The attack uses the hash code implementation for collections and maps to force recursive hash calculation causing a stack overflow. This issue is patched in version 1.4.20 which handles the stack overflow and raises an InputManipulationException instead. A potential workaround for users who only use HashMap or HashSet and whose XML refers these only as default map or set, is to change the default implementation of java.util.Map and java.util per the code example in the referenced advisory. However, this implies that your application does not care about the implementation of the map and all elements are comparable.
